1. MAINTENANCE
A. The two most probable maintenance problems are:
(1)
The accumulation of dirt and mineral deposits in/on the nozzle
(2)
Air and water leaks that may be due to marginal workmanship during installation
but not obvious until after many hours of operations.
B. Nozzle cleaning is recommended at least once a year. Remove the nose cone from the
nozzle body by turning it by hand and mechanically remove deposits by gentle scraping
or scrubbing with a brush or steel wool. Care must be taken not to damage the nozzle
or its surfaces. Wipe clean using a clean dry rag.
C. Leaks in the air and water delivery system could develop over time as the mechanical
seals age. Full nozzle replacement, taken from the spare parts purchased as part of
initial acquisition, is the recommended maintenance procedure if a nozzle should cease
to perform. The nozzle can be repaired back at the workshop using a Level III
maintenance nozzle repair kit. Leaks in the piping can be repaired using standard
plumbing methods.
D. Leak repair kits for the AFE nozzle, Vacuum Valve, Air Regulator and the Water
Regulator are available. Instructions are provided with each kit.
2. SEASONAL MAINTENANCE
A. In most cases there is a humidification season but if this is not the case, it is
recommended that the following actions be conducted once a year.
(1)
A detailed visual leak inspection using soapy water and low pressure (less that 10
psig) of all air and water transport pipes and system components is to be recorded
on a sketch to indicate leak locations and severity.
(2)
Comparison with previous inspection records could indicate systematic problems
as compared to random events.
(3)
Repair leaks and verify the system is fully operational using the procedure
described in the Start Up section of this guide.
(4)
The AIRFOG system is to be shutdown in accordance with the procedure
described in the Shut Down section of this guide.
(5)
Each nozzle shall be cleaned of mineral water deposits and accumulated dirt using
the procedure described in the Maintenance section of this guide.
(6)
Each nozzle should be lubricated using a silicone based lubricant.
(7)
The compressor manual should be consulted for its recommended seasonal
maintenance.
3. SEASONAL STARTUP
A. A detailed visual inspection of all air and water transport pipes and components is to be
recorded on a humidification system sketch to indicate damage, non-conformances and
abnormalities.
B. Comparison with previous inspection records could indicate systematic problems as
compared to random events.
